The = < x set of electrode constraints includes a primary constraint system having first 152- Y and second primary growth constraints and at least one primary connecting =* member, the first and second primary growth constraints separated from each other in the longitudinal direction, wherein the primary constraint ar- 118 162 ray restrains growth of the electrode assembly in the longitudinal direction _ Il 156 such that any increase in the Feret diameter of the electrode assembly in the .4 longitudinal direction over 20 consecutive cycles of the secondary battery M is less than 20%. The set of electrode constraints further includes a sec- en 106 ondary constraint system having first and second secondary growth con- 116 straints connected by at least one secondary connecting member, wherein 0'1 A' the secondary constraint system at least partially restrains growth of the 1-1 electrode assembly in a second direction upon cycling of the secondary N -151 battery. 1-1 0 ei FIG. 1 C
